If you are an aromatherapist, essential oil ingestion is one of the most important skills to have in your toolbox. Today’s clients are using oils in potent concentrations and ingestion regularly. To stay on the cutting edge of the field, today’s aromatherapists must know how to work with clients who choose to ingest oils. Your clients are looking to you for guidance with safety and efficacy. In this 3-week CEU program, you will learn how to formulate safe and effective essential oil products for ingestion, as well as how to integrate ingestion of essential oils into your practice while staying within your scope.

This CEU program provides you a competitive edge in the essential oil field. It includes the foundation of pharmacokinetics, pediatric considerations, product formulation, and a review of the existing scientific evidence on the subject of ingestion. You will also learn through fieldwork with actual clients to master this new skill.

Fortunately, you don’t have to rely on guesswork. There are toxicological guidelines and mathematical calculations that can simplify this task, allowing you to focus on the aspects of aromatherapy you love the most. In this 3-week workshop, Dr. Jessie Hawkins and FSIHS Aromatherapy Chair Christy Hires take you through these processes, empowering you to master them like never before.


This 3- week course is ideal for professional aromatherapists and anyone with an established aromatherapy educational foundation. Whether your expertise in aromatherapy is focused on work individually with clients, developing custom blends, or formulating essential oil based products, knowledge of essential oil research, expertise in ingestion, and a deeper awareness of pathophysiology is necessary to achieve continued success in this rapidly growing field.

If you are a current FSIHS student in the CertAro or DipAS program, this material is all covered in your required coursework. If you are an FSIHS graduate, this course will provide extra practice with EO Ingestion and review what you have already studied.
